Listed packing: 25 kg carton
Package gross weight shown as 26 kg; confirm net weight, palletization, and carton liner type
Listed loading: 16 MT per 20 ft container; verify with palletized loading plan
Request photos of commercial packing, pallet marks, batch labels, and outer carton markings
Confirm availability of sample packing and whether sample COA matches commercial batch format
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Stabilization additive for polypropylene and polyethylene processing
Antioxidant package component for engineering plastics such as ABS, PBT, polyamide, and POM
Additive candidate for synthetic rubber and polymer compounds
Industrial antioxidant candidate for natural or synthetic oils where specifications and compliance permit

How we compare
Sourcing options
Request a specification-matched sample before commercial order
Compare at least two commercial batch COAs for consistency
Ask for factory audit documents or supplier qualification package if the material is critical
Use third-party lab verification for CAS identity, assay, ash, and application-critical impurities
Confirm DG status, HS code, and export paperwork before booking freight
Negotiate trial order quantity with retained sample and pre-shipment COA approval
Request alternative packaging such as palletized cartons if needed for import handling
Human review
Compliance notes
Request current SDS, COA, TDS, specification sheet, and export packing list before order confirmation
Confirm HS code, export declaration name, and whether the product ships as non-dangerous goods or dangerous goods under the relevant transport mode
Verify CAS 6683-19-8, EINECS 229-722-6, and product identity across SDS, COA, label, invoice, and customs documents
No regulatory approval or unrestricted import status should be assumed; buyer should check destination-country chemical inventory and additive-use requirements
For polymer, food-contact, oil, or regulated end uses, request applicable declarations only if relevant and verify independently
Confirm residual impurities, volatile matter, heavy metals if required by the buyer’s application or destination market
Supplier claims should be validated with third-party testing or pre-shipment inspection where compliance risk or application sensitivity is high
